Vivian Said:

Should the title company pay for entire assessment?

We Answered:

They should pay all the back assessments so that your liens are made current. However, it is pretty typical that when public water is made available and the homeowner buys into the system, they have to pay for their portion. It's really a small investment to not have to worry about a septic tank or power outage in the future. $10,000 over 30 years is minimal.

In any case, you'll probably be responsible for the remainder. You could sue, but that money would be best put to use paying the water company instead of a scuzzy lawyer... which would likely end up costing you more than $10,000 and all you'd get is that bill paid off.
